Dental bridges are a common and proven solution for individuals missing one or more teeth. Serving both aesthetic and functional purposes, dental bridges help restore confidence in your smile and ability to chew and speak properly.
A common question that often arises is, how long does a dental bridge last?
This article will explore this question in detail, delving into various factors that affect a bridge's lifespan, care practices, common concerns, and more.
Quick Answer: How Long Does a Dental Bridge Last?
A dental bridge typically lasts at least 5 to 15 years, and many consider this lifespan a success. However, it's not uncommon for a bridge to last much longer, and there's no set time for replacement as long as it looks and functions properly.
Proper care and regular dental check-ups are key to maximizing its lifespan.
Understanding Dental Bridges
Dental bridges are prosthetic devices used to fill gaps caused by missing teeth. There are various types, including traditional, cantilever, and implant-supported bridges. They are custom-made to match the natural teeth, enhancing appearance and functionality.
In simple terms, a dental bridge is a false tooth, known as a pontic, that is held in place by the abutment (anchor) teeth on either side of the gap, effectively "bridging" the space where teeth are missing.
Lifespan of a Dental Bridge
The general expectation for a dental bridge is a lifespan of 5 to 15 years. However, with good oral hygiene and proper care, a bridge can last much longer.
Realistically, most dentists expect to get 20+ years of function from a dental bridge.
The key to maximizing its longevity is regular dental check-ups and prompt attention to any issues that arise. Importantly, there is no absolute “expiration date”; as long as the bridge looks and functions well, it does not need replacement.
Factors Influencing the Lifespan
Materials: Bridges are made from durable materials like zirconia and metal; however, some metal bridges are veneered with porcelain, which can chip or shear over time.
Maintenance and Oral Hygiene: Proper cleaning and routine dental care extend the life of a bridge; decay around the edges (“margins”) of a bridge is a common cause of bridge failure.
Lifestyle Factors: Diet, smoking, and other habits can influence the lifespan; habits like tooth grinding and ice chewing can also destroy bridges.
Regular Dental Check-ups: Early detection of wear or damage helps preserve the bridge.
What Happens to a Dental Bridge Over Time?
With time, a bridge may experience wear or minor shifts in position. Regular monitoring by a dental professional helps detect these changes early, enabling timely intervention if necessary.
Generally speaking, though, the materials in a dental bridge will hold up well for many decades. Replacement of a bridge usually only becomes necessary if decay forms at the edges of the bridge, or in the unlikely event of a bridge fracture.
A bigger concern is receding gums underneath the pontic (“false tooth”) of the bridge. Since there is no tooth root in that location, the jaw bone and gums recede, sometimes resulting in a gap that is unesthetic and harder to keep clean. Depending on the severity of the recession, and the esthetic demands of the patient, this may necessitate replacement of the bridge.
Maintenance and Care
Proper care includes regular brushing and flossing, avoiding certain hard or sticky foods, and professional cleanings. Following these guidelines helps maintain the bridge's appearance and functionality.
You will also notice that flossing a dental bridge is different from flossing your regular teeth — your dentist and/or dental hygienist can show you the proper way to use dental floss under and around a bridge. Some patients also have an easier time keeping a bridge clean with the use of water flossers.
What are the Disadvantages of a Dental Bridge?
Some potential drawbacks include:
The need for adjacent teeth alteration
Difficulty in cleaning under the bridge
Potential long-term wear on supporting teeth.
Loss of bone & gums in the area of the missing tooth
Is Replacing a Dental Bridge Painful?
Replacement is generally a straightforward procedure. While some discomfort might occur, it's typically less painful than the initial placement.
Common Concerns with Dental Bridges (FAQs)
Can food get under a dental bridge? Yes, but proper cleaning techniques minimize this risk.
What foods should you avoid with a bridge? Hard or sticky foods can cause damage; a dentist can provide specific recommendations.
Alternatives to Dental Bridges
While dental bridges are a popular solution for replacing missing teeth, they're not the only option available. Depending on individual needs, preferences, and oral health, one might consider the following alternatives:
Dental Implants: Dental implants are a more permanent solution that involves inserting a titanium post into the jawbone, which serves as a root for a replacement tooth. Implants are known for their stability, natural appearance, and long lifespan, often lasting a lifetime with proper care. However, they tend to be more expensive and require a longer healing period compared to dental bridges.
Partial Dentures: Partial dentures are removable appliances that can replace one or more missing teeth. They're typically less expensive than bridges or implants but will not provide the same level of comfort and stability. Partial dentures can be a good option for those who are not candidates for bridges or implants or prefer a less invasive procedure.
Resin-Bonded Bridge (Maryland Bridge): This type of bridge is similar to a traditional dental bridge but uses metal wings bonded to the adjacent teeth rather than crowns. It's often used for front teeth and can be a less invasive and more cost-effective option. However, it may not be suitable for areas of the mouth that experience strong biting forces, and these bridges are very prone to fracturing and de-bonding.
Doing Nothing: Depending on the location and reason for the missing tooth, some individuals might choose not to replace it at all. While this option avoids the costs and procedures associated with dental restoration, it may lead to long-term problems such as shifting teeth, bite issues, esthetic concerns, and loss of bone.
Final Thoughts
The lifespan of a dental bridge is influenced by various factors, from the materials used to individual care practices.
While 5 to 15 years is often considered successful, many bridges last much longer.
Regular dental check-ups, proper maintenance, and adherence to professional guidance can help ensure your bridge serves you well for many years. Your dental professional remains the best resource for personalized advice and care.
